What is Postman?
Postman starts with an API request: a developer sets the endpoint, method, authorization, and payload, then inspects the response. Collections group related requests with examples, documentation, variables, and scripts, making an API workflow shareable with other developers. The current product also supports broader design and testing workflows; the useful starting point is a maintained collection that reflects the live API.

PostmanTesting & QADesign, send, and test API requests
Key capabilities
- Request client: construct and inspect supported API calls.
- Collections: organize requests, examples, scripts, and documentation.
- Variables and environments: reuse requests against different targets.
- Collection runs: execute saved requests and tests manually or in automated workflows.
Postman can give developers and integrators a common, executable description of API behavior. Its current documentation was checked 27 September 2026. Adoption figures and claims of universal protocol support were removed because neither is needed to explain the workflow.
